Dear all,
We are easily able to obtain mechanical properties (such as elastic modulus, Poisson's ratio and ...) of a unidirectional lamina composite by means of rule-of-mixture. 
For instance, in case of "longitudinal loading", strength of the fiber-reinforced composite for long continuous fibers will be like:
Ec=Ef*Vf+Em*Vm.

I have two main questions: 
First, are these relations (longitudinal and transverse loading) hold for bidirectional composite? if not, how can we obtain relative elastic modulus?

A perspective paper on material failure theory and applications

Submitted by Yonggang Huang on

The Perspective papers published in Journal of Applied Mechanics have attracted a lot of readers, such as the first perspective paper by Huajian Gao (Brown University) which has been downloaded for >8,000 times.  A perspective paper, as invited by the editor of JAM, is very short (2~3 pages) and easy to read (like Readers' Digest) to reveal some emerging directions, or some important discoveries in clasical directions, in mechanics.

How to develop a new constitutive model from scratch?

Constitutive model
Dear all  iMechanica,
 
I wonder if there is any good  material on constitutive modeling that explains how to develop a new constitutive model from scratch, e.g. from the experimental data say uniaxial tension and compression. Where should one start to develop a new constitutive model? What laws should the model obey?
